Abstract

The invention relates to a process and a device for flue gas desulphurization using the following reaction: SO2+Br2+2 H2O->H2SO4+2 HBr The hydrobromic acid thus formed is split up by electrolysis into hydrogen and bromine. The sulphuric acid thus produced is brought to a saleable concentration rate of at least 90% in two successive concentrators (1, 2), the post-concentrator being fed with high temperature flue gases which are withdrawn immediately behind the economizer of the power plant. A partial flow of the flue gases to be cleaned traverses a heat exchanger (6), in which the cleaned flue gases are reheated to a temperature level which is compatible with the chimney requirements.
